Description

Technical Field

[0001] This utility model relates to a desktop ultrasonic cleaner for biological testing, belonging to the field of ultrasonic cleaning technology. Background Technology

[0002] Biological testing typically involves the analysis of microorganisms, cells, molecules, etc. After biological testing, organic residues may remain in the sample containers and test kit components. In order to facilitate continued use, it is often necessary to clean the sample containers and test kits. To avoid damage to the equipment caused by incomplete manual cleaning or excessive wiping, and to ensure the integrity and performance of the equipment, ultrasonic cleaners are often used to clean the devices.

[0003] Currently, when cleaning equipment, it is necessary to place the equipment in a cleaning basket inside the cleaning tank and use ultrasound to clean sample containers and reagent kits. In order to prevent items from being moved out of the cleaning basket during cleaning, the depth of the cleaning basket is set to be relatively deep. Due to the depth of the cleaning basket, it is inconvenient for staff to place or remove products from the cleaning basket. To address this, we propose a benchtop ultrasonic cleaner for biological testing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a desktop ultrasonic cleaner for biological testing, which solves the problem in the prior art that it is inconvenient for staff to place or take out products from the cleaning basket due to its depth.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A benchtop ultrasonic cleaner for biological testing includes a cleaning chamber. A limiting seat is fixedly connected to the inner wall of the cleaning chamber. A limiting post is vertically inserted into the interior of the limiting seat. A limiting frame is fixedly connected to the bottom end of the limiting post. A sliding plate is sleeved on the outer surface of the limiting post. A spring is provided between the sliding plate and the limiting frame. A cleaning basket is fixedly installed on the sliding plate. A limiting hole is opened in the vertical direction in the cleaning basket. Placement racks are fixedly connected to both ends of the limiting frame extending through the limiting hole into the interior of the cleaning basket. A connecting plate is fixedly connected to the limiting frame. A lifting component is fixedly connected to the inner top wall of the connecting plate.

[0007] By adopting the above technical solution, when staff need to remove the cleaned equipment, they can activate the electric push rod. The electric push rod moves the connecting plate upward, which in turn moves the limiting frame upward. Due to the support of the spring, the upward movement of the limiting frame moves the cleaning basket upward as well. When the sliding plate contacts the limiting seat, the limiting seat blocks the sliding plate as the limiting frame moves upward, compressing the spring. As the limiting frame continues to move upward, the spring is continuously compressed, causing the placement rack to move upward from the inner bottom of the cleaning basket, thus changing the placement rack's position within the cleaning basket. With the placement of the rack in the center, staff can directly retrieve the cleaned instruments from the rack without having to retrieve them from the bottom of the cleaning basket, making retrieval more convenient. After retrieval, staff can directly place other unwashed instruments on the rack and then activate the electric push rod. As the electric push rod retracts, it controls the rack to move downwards, allowing it to be moved back to the bottom of the cleaning basket. This makes instrument placement more convenient and effortless. Because the rack can move inside the cleaning basket, its depth can be adjusted, minimizing the height difference between the instruments and the rack, effectively reducing the probability of damage during placement.

[0008] The present invention is further configured such that a limiting block is fixedly connected to the end of the limiting post away from the limiting frame.

[0009] By adopting the above technical solution, the limiting block can limit the movement of the limiting post inside the limiting seat, effectively preventing the limiting post from separating from the limiting seat during its downward movement. Furthermore, due to the obstruction of the limiting block, the downward position of the limiting post can be prevented from being too low.

[0010] The present invention is further configured such that: the lifting assembly includes an electric push rod, the top end of which is fixedly installed on the inner top wall of the connecting plate, an mounting plate is fixedly connected to the cleaning tank, and the end of the electric push rod away from the connecting plate is fixedly connected to the mounting plate.

[0011] By adopting the above technical solution, the mounting plate can provide support for the electric linear actuator, making the installation of the electric linear actuator more stable.

[0012] The present invention is further configured such that: a slag discharge pipe is fixedly connected to the side of the cleaning tank facing the ground, and a sealing cap is threadedly connected to the outer surface of the bottom end of the slag discharge pipe.

[0013] By adopting the above technical solution, the slag discharge pipe can discharge the cleaning liquid inside the cleaning tank, and the staff can open the sealing cover to discharge the debris accumulated inside the slag discharge pipe and clean the debris.

[0014] The present invention is further configured such that: a circulation pump is fixedly connected to one side of the cleaning tank, a liquid guide pipe is fixedly connected to the water inlet end of the circulation pump, the end of the liquid guide pipe away from the circulation pump is fixedly connected to the outer surface of the slag discharge pipe, and a return pipe is fixedly connected to the water outlet end of the circulation pump, the end of the return pipe away from the circulation pump passes through the cleaning tank and extends into the interior of the cleaning tank.

[0015] The present invention is further configured such that a filter screen is fixedly installed inside the liquid guide tube near the slag discharge tube.

[0016] By adopting the above technical solution, when using the ultrasonic cleaner, the operator can start the circulation pump. The cleaning fluid inside the cleaning tank will pass through the slag discharge pipe, then through the liquid guide pipe, and then through the return pipe to be transported back into the cleaning tank. During the transportation of the cleaning fluid, impurities will be blocked by the filter screen and retained inside the slag discharge pipe. Through the circulation of the cleaning fluid, the cleaning debris inside the cleaning tank can be collected inside the slag discharge pipe. This not only facilitates the collection of debris, but also makes the cleaning fluid inside the cleaning tank cleaner, which is beneficial for ultrasonic cleaning of equipment.

[0017] The present invention is further provided that a support frame is fixedly connected to the cleaning tank.

[0018] By adopting the above technical solution, the support frame can support the cleaning box and connect it to the ground with bolts, making the ultrasonic cleaner more stable.

[0019] The beneficial effects of this utility model are as follows: When staff need to remove the cleaned equipment, they can activate the electric push rod. The electric push rod drives the connecting plate upward, which in turn drives the limiting frame upward. Due to the support of the spring, the limiting frame moves upward, causing the cleaning basket to move upward as well. When the sliding plate contacts the limiting seat, the limiting seat blocks the sliding plate as the limiting frame moves upward, thus compressing the spring. As the limiting frame continues to move upward, the spring is continuously compressed, allowing the placement rack to move upward from the inner bottom of the cleaning basket, changing the position of the placement rack within the cleaning basket. The internal location allows staff to directly retrieve cleaned instruments from the rack without having to retrieve them from the bottom of the cleaning basket, making retrieval more convenient. After retrieval, staff can place other unwashed instruments directly on the rack and then activate the electric push rod. As the electric push rod retracts, it controls the rack to move downwards, allowing it to be moved back to the bottom of the cleaning basket. This makes instrument placement more convenient and effortless. Because the rack can move inside the cleaning basket, its depth can be adjusted, minimizing the height difference between the instruments and the rack, effectively reducing the probability of damage during placement.

[0026] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0027] Example 1

[0028] like Figures 1 to 4 As shown, a benchtop ultrasonic cleaner for biological testing includes a cleaning tank 1. The cleaning tank 1 contains an ultrasonic component for cleaning equipment. The ultrasonic component mainly includes a transducer and an ultrasonic generator, which are electrically connected via wires. The transducer is installed inside the cleaning tank 1. The ultrasonic generator generates high-frequency electrical signals, which the transducer converts into mechanical vibration energy, thus cleaning the equipment inside the cleaning fluid. A limiting seat 2 is fixedly connected to the inner wall of the cleaning tank 1, and a limiting device is vertically inserted into the inside of the limiting seat 2. The bottom end of the column 3 is fixedly connected to the limiting frame 4. The outer surface of the limiting column 3 is fitted with a sliding plate 5. A spring 6 is provided between the sliding plate 5 and the limiting frame 4. The spring 6 is normally in a supporting state and is fitted on the outer surface of the limiting column 3. A cleaning basket 8 is fixedly installed on the sliding plate 5. The cleaning basket 8 has a limiting hole 11 in the vertical direction. The two ends of the limiting frame 4 extending through the limiting hole 11 into the interior of the cleaning basket 8 are fixedly connected to the placement rack 7. A connecting plate 9 is fixedly connected to the limiting frame 4. A lifting component is fixedly connected to the inner top wall of the connecting plate 9. The lifting component can control the lifting of the connecting plate 9.

[0029] like Figure 1As shown, the end of the limiting post 3 away from the limiting frame 4 is fixedly connected to the limiting block 12. The bottom surface dimension of the limiting block 12 is larger than the inner diameter of the opening inside the limiting seat 2. When the limiting block 12 moves downward with the limiting post 3, it is blocked by the limiting seat 2, which prevents the limiting block 12 from passing through the limiting seat 2.

[0030] As shown in Figure 2, the lifting assembly includes an electric push rod 10. The top end of the electric push rod 10 is fixedly installed on the inner top wall of the connecting plate 9. An mounting plate 13 is fixedly connected to the cleaning tank 1. The end of the electric push rod 10 away from the connecting plate 9 is fixedly connected to the mounting plate 13.

[0031] like Figure 3 and Figure 5 As shown, a slag discharge pipe 14 is fixedly connected to the side of the cleaning tank 1 facing the ground. A sealing cap 15 is threadedly connected to the outer surface of the bottom end of the slag discharge pipe 14. The outer surface of the bottom end of the slag discharge pipe 14 is provided with external threads, and the inner wall of the sealing cap 15 is provided with internal threads, with the external threads matching the internal threads. A circulation pump 16 is fixedly connected to one side of the cleaning tank 1. A liquid guide pipe 17 is fixedly connected to the water inlet end of the circulation pump 16. The end of the liquid guide pipe 17 away from the circulation pump 16 is fixedly connected to the outer surface of the slag discharge pipe 14. A return pipe 18 is fixedly connected to the outlet end of the circulating pump 16. The end of the return pipe 18 away from the circulating pump 16 passes through the cleaning tank 1 and extends into the interior of the cleaning tank 1. The outlet port of the return pipe 18 faces the inner bottom wall of the cleaning tank 1. A filter screen 19 is fixedly installed inside the liquid guide pipe 17 near the slag discharge pipe 14. During the circulation of the cleaning liquid, the filter screen 19 can block impurities, reduce the amount of impurities entering the interior of the circulating pump 16 through the filter screen 19, and reduce the probability of damage to the circulating pump 16.

[0032] like Figure 3 As shown, a support frame 20 is fixedly connected to the cleaning tank 1.

[0033] When staff need to remove the cleaned equipment, they can activate the electric push rod 10. The electric push rod 10 moves the connecting plate 9 upward, which in turn moves the limiting frame 4 upward. Due to the support of the spring 6, the limiting frame 4 moves upward, causing the cleaning basket 8 to move upward as well. When the sliding plate 5 contacts the limiting seat 2, the limiting seat 2 blocks the sliding plate 5 as the limiting frame 4 moves upward, thus compressing the spring 6. As the limiting frame 4 continues to move upward, the spring 6 is continuously compressed, causing the placement rack 7 to move upward from the inner bottom of the cleaning basket 8. This changes the position of the placement rack 7 inside the cleaning basket 8, allowing staff to directly retrieve the cleaned equipment from the placement rack 7 without having to retrieve it from elsewhere. The bottom of the cleaning basket 8 is easily accessible, making it more convenient to retrieve items. After retrieval, staff can directly place other unwashed equipment on the placement rack 7. Then, the electric push rod 10 is activated. As the electric push rod 10 retracts, the placement rack 7 can be moved downwards, allowing it to be moved back to the bottom of the cleaning basket 8. This makes equipment placement more convenient and effortless. Since the placement rack 7 can move inside the cleaning basket 8, its depth can be adjusted, minimizing the height difference between the equipment and the placement rack 7 when placing equipment, effectively reducing the probability of damage during equipment placement. The limiting hole 11 limits the limiting frame 4, allowing it to slide vertically within the limiting hole 11, ensuring that the limiting frame 4 moves more smoothly and is less prone to positional deviation.

[0034] The limiting block 12 can limit the movement of the limiting post 3 inside the limiting seat 2, effectively preventing the limiting post 3 from separating from the limiting seat 2 during downward movement. Furthermore, due to the obstruction of the limiting block 12, the limiting post 3 can be prevented from descending too low.

[0035] When using the ultrasonic cleaner, the operator can start the circulation pump 16. The cleaning fluid inside the cleaning tank 1 will pass through the slag discharge pipe 14, then through the liquid guide pipe 17, and then through the return pipe 18 to be transported back into the cleaning tank 1. During the transportation of the cleaning fluid, impurities will be blocked by the filter screen 19 and retained inside the slag discharge pipe 14. Through the circulation of the cleaning fluid, the cleaning debris inside the cleaning tank 1 can be collected inside the slag discharge pipe 14. This not only facilitates the collection of debris, but also makes the cleaning fluid inside the cleaning tank 1 cleaner, which is beneficial for ultrasonic cleaning of equipment.

[0036] When a lot of debris accumulates inside the slag discharge pipe 14, the staff can open the sealing cover 15 at the bottom of the slag discharge pipe 14 to discharge the debris. When the filter screen 19 is clogged, the staff can take a cleaning brush and insert it into the slag discharge pipe 14 from the bottom. By contacting the filter screen 19 with the cleaning brush, the filter screen 19 can be cleaned and the debris on the filter screen 19 can be washed off.

[0037] The support frame 20 can support the cleaning box 1 and is connected to the ground by bolts, which can make the ultrasonic cleaner more stable.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
